ThunderSpark Distributor Cap P/N:925-1043

Keep high-voltage spark reaching the right cylinder with the ThunderSpark Distributor Cap 925-1043, an OE Replacement cap for conventional distributor-based ignition systems. It installs as a direct-fit replacement for the 1989-1991 Mazda MPV — see the Buyer's Guide tab for the full engine-level application details. The distributor cap directs high-voltage current from the ignition coil to the correct spark plug through the rotor and internal terminals; over time a cap can develop carbon tracking, cracking, or corrosion, which may lead to misfires and hard starting.

• OE Replacement Quality: Built to meet OE specs for terminal alignment, dielectric strength, and conductive path precision.
• Heat-Resistant Materials: Constructed with high-dielectric compounds to withstand high voltage, thermal cycling, and engine vibration.
• Directs High-Voltage Spark: Routes ignition coil output to the correct cylinder to support proper firing order.
• Exact OE Fit: Designed to fit the original distributor housing and maintain a secure connection with the rotor and ignition wires.

If a cracked or worn cap is the cause of misfires or hard starts, this unit replaces it during a tune-up or ignition repair.
